MACHINE FOR INSERTING FASTENING-S.

To all whom it may concern:

Be it known that I, FREDERICK H. PERRY, a citizen of the United States,residing at Beverly, in the county of Essex and Commonwealth ofMassachusetts, have invented certain Improvements in Machines forInserting Fastenings, of which the following description, in connectionwith the accompanying drawings, is a specification, like referencecharacters on the drawings indicating like parts in the several figures.

This invention rel-.1 tes to machines for inserting in certain classesof stock, more par ticularly leather, a short length of suitablematerial, preferably metal, which may be so short as to form merely aslug used for purposes of ornamentation or resisting wear, or may be ofsuch length as to form a peg or nail used for securing together two ormore layers of the stock into which it is inserted.

As machines embodying this invention may be used to insert devices ofthe kind described of any desired length, for convenience the termfastening will hereinafter he used generically to designate any devicethat maybe used for any of the purposes named, and wherever the wordfastening occurs herein it should be held to include a peg, nail orslug, or all of these, as the context may admit or require.

h'lore particularly, the type of machine to which this invention relatesis shown in United States Letters Patent to Stillman Robinson, No.591,658, dated October 12, 1897.

In machines of the type above referred to fastening material is fedthrough a stationary quill into a passageway in a carrier plate, whichis thereafter moved for severing said material to form a fastening andfor placing the fastening in position to be acted upon by a driver whichforces it into the stock. A. cutting device is provided for forming apoint on the end of the fastening, and during the operation of saidcutting device the fastening material is held in position in the quillby a presser block which is mounted on the swing plate that carries thecutting device. The swing plate is actuated by mechanism operated fromthe main shaft, and the carrier plate is actuated by the Specificationof Letters Patent.

movement of the swing plate through a connection therewith.

One of the objects of this invention is to provide improved means forholding the fastening material in position in the quill while thecutting device is operating upon said material.

Another object is to provide a chip re,- mover for ejecting the chipthat is cut from the fastening in forming a point thereon.

Another object is to provide an improved connection between the swingplate and the carrier plate for imparting movement from one to theother.

Other advantages of my invention will be hereinafter pointed out.

In the drawings :Figure 1 is a front elevation of the head of themachine; Figs. 2, 3 and t are detail plan views of the mechanism withall above the swing plate removed, and partly in section, showing;first, the swing and carrier plates in the positions they will occupywhen the fastening material is being fed into the passageway in thelatter; second, the position of the carrier plate at the end of itsforward and lateral movement when a fastening is in position to bedriven; and third, the position of the swing plate at the end of itsforward and lateral movement, the engaging lug thereon having passed outof engagement with the shoulder on the carrier plate; Figs. 5 and 6 aredetail views of the improved quill; Figs. 7 and S are detail sectionalviews taken through the head of the machine, as indicated by line a'.cof Fig. 2, and y z of Fig. 3, showing the carrier plate first, inposition for receiving the fastening material; and second, in positionfor a fastening to be driven therefrom; and Fig. 9 is an elevationshowing a portion of the right-hand side of the head of the machine.

Referring to the drawings, 2 designates a base supporting a head 4-which carries the main shaft 6 that has mounted thereon a cam S. Saidcam is provided with a toe 9 that cooperates with a block 11 on a driverbar 10 for elevating sa'id bar and its attached driver 13 after theyhave been depressed by the driver-actuating spring 12. The material fromwhich the fastenings are formed, which is herein shown as wlre 15, issupported in a reel 14, said wire being fed downwardly by rolls18 and 20through a passage way 19in a quill'16 carried by a top'plate 22 and intoa tube 34 mounted in a carrier plate 32. The quill 16 is also providedwith a driver passageway 17.] Mounted some dis tance below'the top plate22 is a bottom plate 28 that is fastened to the head of. the

.24 and 26 projecting downwardly fromthe to late. Tube 34 is clam 'iedin the carrier P P 1 l. plate by a screw 34 and wnen the carrier plateis in position for receiving the wire, as

shown in Fig. 2, the opening in said tube will be in alinement with theWire passageway 19in the quill 16. As the carrier plate is actuated toplace the opening in the tube 34in alinement with the passageway 17 theupper end of said tube and the lower end of said quill cooperate toshear off the wire.

A cuttingdevice, comprising a knife 40, is

, held in the swing plate30 by a clamp 42,

and bearing upon the end of the shank of said'knife is an adjustingscrew 44 on which a knurled nut 46 is threaded, said nut being confinedbetween lugs 48 and 50 on the swing plate. The knife can be adjusted asits cutting edge wears away by loosening the clamp 42 and turning thenut to cause the s crew 44 to move forwardly, said screw being preventedfrom rotary movement by a pin141 which enters a slot in the lug 50, asshown in Fig. 9. .The nut 46'is held from accidental movement by afriction washer 49 interposed between the lug 48 and said nut. A chipremover 54 is pivoted to the swing plate at 56 and operates to eject thechip which the knife 40 removes in forming a point on a fastening. Aspring 58 seated in theswing' plate bears continuously against theacting end of the chip remover tending to forceiit outwardly, but thisend isheld substantially flushwith the cutting edge of lmife'40. bymeans of an adjusting screw 55 also mounted in the swing plate, as shownin Fig. 2; By meansof screwe55 the relation between the chip remover andknife maybe kept constant no matter what the adjustment of the latter.

;The quill 16, which forms one of the most important features of myinvention, has its lower end cut away, as shown in Fig.6, to

eXpose the passageway 19, so that the knife 40 canengage one side of thewire and remove a portion thereof to form' a point on the fastening. For holding the wire securely in position while the 'knife is operatingthereon, the quill is provided with a movable section 60 connectedthereto by a pin 61 which rests in a notch 62 in the body of the quill,the lower end of said movable section being engaged and forced inwardlyto bear upon the wire by a spring 64 that is confined in a recess in thetop plate, see Figs. 7 and 8. When the wire is held by a clamp of thischaracter it is practically impossible for it to be displaced from thelower end .of the passageway 19 when the knife is operating thereon,because quite a portion of the wire is engaged by the movable section ofthe quill. Moreover as said movable ,sectionis held yieldingly inengagement with the wire any inequality in'the size of the wire will notprevent it from being clamped properly. The movable section 60 is provided with a projecting lug 59, as shown in Fig, 5,and when the"quillis' in position, the lugi's adaptedto be seated in a recess in thetop plate, said quill being held in position by a clamp which isfastened to the top plate by screws 68. This construction permits thequill to be removed easily andinsures its being positioned properlywhen'it is replaced. Projecting rearwardly from the swing plate is anarm which is connected to the lower end of an actuating lever .80 by ablock-72 having a pin 74 which enters an opening in the lower end oflever 80, said block also having an opening to receive a pin 71projecting downwardly frointhe arm .70. The lever '80 isfulcrumedon apin 82: carried by links 84 and. 86 which project. 1 from a hub that isfulcrumed on a stud shaft .79 mounted in the head ofthe machine.

the upper end of said lever is an eccentric strap which engages aneccentric on the 'inain shaft, as shown in dotted lines in; Fig.

1, whereby therotary movement of I said shaft will cause the lever 80 tooscillate on its pivot thus actuating the 'swing plate, and will alsorock the links 84 and 86 thus actuating the feeding roll 18, ashereinafter described.

The swing plate is providedwith down-' wardly projecting lugs 90 and 91,shown in dotted lines in Figs. 2, 3 and 4, which 00- operate withshoulders 92 and .93 formed on an arm of the carrier phr s that when theswing plate is actuated the lugs thereon will engage said shoulders andmove the carrier plate therewith. Preferably the 7 lugs and thecooperating shoulders are formed of hardened steel so that continual usedoes not causethese parts to wear away.

When the carrier plate'is inthe position shown in 2 thetube 84willb'e'in a'linement with the wire passageway 19 in the quill, and thelugs 90' and91 on the swing plate will stand somedistance -to the leftof the shoulders 92 and 98 on the carrier plate. .lVhen the swing plate;is moved forward and laterally, in the direction of the arrow in .Fig.2, the carrier plate will remain at rest until the lug 90 comes intoengagement with the shoulder 92, and thereswing plate until said lug andshoulder pass out of engagement, as shown in Fig. 3, the disengagementof the lug and shoulder being due to the fact that the swing and carrierplates oscillate about diflerent centers.

The forward and lateral movement of the swing plate causes the knife 40to shear off a chip from one side of the wire standing in the exposedportion of the passageway 19 in the quill, for forming a point on thefastening which is to be driven at the next cycle of operations. Themovement of the carrier plate immediately thereafter severs the wire toform a fastening, and also carries said fastening into alinement withthe driver passageway 17 in the quill, so that as driver 13 descends thefastening will be driven from the tube 3 1 through the throat block andinto the stock. In the forward and lateral movement of the swing platethe chip remover engages the wire and is rocked slightly against thestress of spring 58, as shown in F On the severance of the (hip itpasses on to the end of the chip remover, which, on passing out ofengagement with the wire, is forced outwardly by spring ejecting thechip from the machine, the lower end of the quill being beveled as shownat 106 to provide a clearance for this purpose.

After the lug 90 passes out of engagement with the shoulder 92, theswing plate continues to move, in order to lock the carrier plate in theposition to which the swing plate just previously adjusted it, untilitarrives in the position shown in Fig. 4. When the swing plate is movedin the opposite (lirection the lug 91 will engage the shoulder 03 andwill return the carrier plate to its normal position shown in Fig. 2,the wire being then fed into the tube 34 in readi ness to serve as thenext fastening, on which the point was formed at the beginning of thiscycle of operations.

Qhe feed roll 18 is mounted on the stud shaft 79, which at its outer endis supported in a bearing 13 projecting upwardly from the top plate, andsaid roll is provided with a groove 23 for receiving the fasteningmaterial, which is also acted upon by the yielding roll 20. l astened tothe hub of the feed roll 18 is a ratchet wheel 31 and pivotally mountedon the end of pin 82 are a plurality of different length pawls 9d and 96which engage and rotate the ratchet wheel 31 as the lever 80 isactuated.

l or changing the length of the fastenings to be inserted, apawl-controlling shield 95 is provided for varying the feed of the wire,said shield being fastened to a regulating lever 91. fulcrumed on thestud shaft 79. As shown in Fig. 1, the pawl-controlling shield partiallyencircles the ratchet wheel 31, so that during the first portion oftheir forward movement said pawls will ride-upon the shield 95.Consequently by changing the position of said shield the time at whichthe pawls engage the ratchet wheel will be changed and thus the feed ofthe wire will be varied. For holding the shield in any position to whichit may be adjusted, a dog 99 is pivoted to the top plate and is adaptedto engage teeth formed on the side of lever 97, a spring 100 bearingagainst the inner end of said dog to hold it in engagement with saidteeth.

In order that the operator may change the feed of the wire to producethe longest or the shortest fastenings without accurately determiningthe position of the pawlcontrolling shield, the lever 97 is providedwith a pin 95 which is adapted to engage stops 105 and 107 when thepawl-controlling shield is in either of its extreme positions, saidstops being movably mounted in the head, where they are retained inadjusted position by a set screw 109, see Fig. l.

A guide 101 is fastened to the bearing 13 and extends from the upper endof the quill to the feed roll, so as to prevent the fastening materialfrom bending as it is being fed into said quill.
